Firstly, Robles was brought in as a no2 keeper, and that's his job until Howard gets dropped etc, so we won't see much of him.
Deulofeu is a kid that has been sent to us to help him develop. Let's not expect too much from this. The fact he has been played is mainly an opportunity for us to see him, and him to get experience. I think he's done ok so far.
Kone has looked ok to me, and we've seen nothing of him to judge yet. Had his shots gone in we'd have been praising him, but that's the fine line.
Alcaraz is a waste of wages at the moment and needs to get fit. Poor signing.
Barry is helping out, but not as great as some fans seem to be getting excited about. I would call his performances good enough to keep his place, but certainly not exceptional.
McCarthy: Too little to judge. Yesterday he played well among many players who didn't, but fingers crossed he will prove to be a great signing.
Lukaku: Good striker and passer, but looks several weeks behind in terms of stamina and I think we should cut his minutes down for now.
